Andreas Kling	c3351d4b9f	Kernel: Make VirtualFileSystem functions take credentials as input ... Instead of getting credentials from Process::current(), we now require that they be provided as input to the various VFS functions. This ensures that an atomic set of credentials is used throughout an entire VFS operation.	2022-08-21 16:02:24 +02:00
Andreas Kling	122d7d9533	Kernel: Add Credentials to hold a set of user and group IDs ... This patch adds a new object to hold a Process's user credentials: - UID, EUID, SUID - GID, EGID, SGID, extra GIDs Credentials are immutable and child processes initially inherit the Credentials object from their parent. Whenever a process changes one or more of its user/group IDs, a new Credentials object is constructed. Any code that wants to inspect and act on a set of credentials can now do so without worrying about data races.	2022-08-20 18:32:50 +02:00
